1, long-term sleep deprivation can cause memory impairment. University of California, Berkeley researchers found that long-term sleep deprivation will not only affect memory, but also may cause Alzheimer’s disease. When you sleep, brain cells remove harmful substances in the brain, but if you do not sleep enough, it will have a negative impact on brain cells. The graph above shows the amount of harmful substances in the brain after 7-8 hours of sleep and 4-5 hours of sleep. 2, long-term under stress will cause brain damage. Long-term acceptance of stress and failure to resolve it will cause memory, learning and self-control and other abilities are impaired, making you feel irritable, anxious and inattentive. Above: damaged brain, reading information in half of the test will often be “disconnected”. 3, “love” and “hate” have more in common than you think. British scientists found that love and hate originate from similar blocks of the brain. Unlike “hate” is the emergence of “love” emotion, the block responsible for judgment and logical thinking will be significantly reduced activity. 4, the brain is very sensitive to dehydration. The brain is composed of 80% water, and just a small loss of water (about 2%) can reduce the ability to focus and be alert, and reduce short-term memory and other cognitive abilities. A dehydrated brain will “shrink” as shown above. 5. Pregnancy can change the structure of the brain. Scientists have confirmed that pregnancy reduces the gray matter in the brain responsible for social cognition and understanding of others, because it is necessary to strengthen the connection between mother and baby, so that the woman can be the first to notice the needs of the child and more alert to external crises. 6, ingesting too much sugar will reduce memory, reducing learning ability. Consuming too much fructose will reduce the brain’s reaction speed, and reduce the ability to learn, memory and focus. Because too much sugar will damage the nerve conduction substances in the brain. Scientists have found that industrial sugar added to drinks, spices, sauces and baby food is more harmful; foods containing omega-3 fatty acids (such as fish, nuts and fish oil) can repair the damage caused by sugar. 7, love and motherhood are very similar. Scientists scanned brain activity found that the love of love and maternal love triggered by the brain response is very similar, but there are some slight differences. For example, falling in love will touch the brain blocks related to sexual desire, motherhood will not. In addition, falling in love decreases the perception of anxiety and fear and enhances feelings of pleasure. Maternal love, on the other hand, touches the brain blocks responsible for the formation of feelings. 8, painting can stimulate the brain’s ability to function. Studies have found that painting and other artistic creations or enjoying works of art can enhance the interaction of different parts of the brain and slow down the rate of brain aging. Scientists study the impact of art on the brains of older people aged 62 to 70, they will be divided into two groups, a group of painting class, a group of art history class, found that the effect of painting class that group more obvious. 9, reading is the perfect way to train the brain. Oxford University researchers confirmed that reading can strengthen the brain’s cognitive ability, in addition to activating the brain’s usual less active blocks. When reading, the brain blocks responsible for concentration and understanding will become active. Note that watching TV or playing video games does not have this effect.
